9. EDTA and other similar chelating agents are frequently used in cleaning products. Briefly explain how a cleaning product containing EDTA can aid in removing hard water soap scum from a sink. Would the presence of EDTA in a soap powder help prevent soap scum formation in hard water? Briefly explain. a) Yes, it will help, cause EDTA is a chelating agent able to bind to Ca2+ and Mg 2+ O ions (responsible for water hardness and soap scum formation) and therefore making these two ions inactive b) Yes, it will help, cause EDTA is a chelating agent able to bind only to Ca2+ O (responsible for water hardness and soap scum formation) and therefore making this ion inactive c) Yes, it will help, cause EDTA is a chelating agent able to bind only to Mg2+ (responsible for water hardness and soap scum formation) and therefore making this ion inactive O d) It will not help at all. It is complicated!
